But I would expect -i "'11173 java'" or -i '"11173 java"' to work.

The nested quoting is unusual (but documented in the pmval(1) man page) 
as a result of the "special" significance of white space in an external 
instance name, i.e. an instance name must be unique across an instance 
domain up to the first white space in the name.
There are only a few examples of instance names than contain spaces ... 
but this does include all of the process-based ones and the load average.
